Pesticides safeguard agricultural yields by controlling insects, fungi, and weeds. However, they also enter streams and damage the aquatic communities. In a nationwide monitoring program, scientists led by the Helmholtz Centre for Environmental Research have shown that the governmental thresholds for pesticides are too high and that these levels are still exceeded in over 80% of water bodies. The loss of biodiversity can only be halted if the environmental risk assessment of pesticides is revised.
Marine scientists assessed the risk posed by small-scale fisheries to all 72 species of toothed whales found throughout the world's oceans. They found that this risk was highest in the Central Indo-Pacific, Temperate Northern Pacific, Temperate South America and the Western Indo-Pacific.
Conditions during Baltic herring spawning may have cascading effects on the whole Baltic ecosystem.
Just two weeks of citalopram exposure caused changes in crayfish behavior, with the potential to disrupt stream ecosystem processes like nutrient cycling, oxygen levels, and algal growth.
Killer whales have complex social structures including close "friendships", according to a new study that used drones to film the animals.
Expose crayfish to antidepressants, and they become more outgoing -- but that might not be such a positive thing for these freshwater crustaceans, according to a new study.
POSTECH-Dong-A University College of Medicine joint research team presents an innovative eye surface reconstruction method using the photocrosslinked mussel adhesive protein.
A study by University of Rhode Island researchers using a seldom-used methodology turned up many more Eastern spadefoots, an endangered primitive frog, than they expected.
A new study in Proceedings of the National Academy of Sciences uncovers where much of the carbonate consumption in the deep sea is happening - a process that prevents its escape into Earth's atmosphere. Researchers from Harvard and Boston University collected and examined methane-eating microbes from seven geologically diverse seafloor seeps and found that the carbonate rocks from all sites host methane-oxidizing microbial communities with the highest rates of methane consumption.
The concentration of potentially toxic metals is increasing in the population of the franciscana dolphin --a small cetacean, endemic from the Rio de la Plata and an endangered species-- according to a study led by a team of the Faculty of Biology and the Biodiversity Research Institute (IRBio), published in the journal Science of The Total Environment.
